Method Detail

numVertexAttachments

public abstract int numVertexAttachments()

getVertexAttachment

public abstract PointAttachment getVertexAttachment(int idx)

Description copied from class: DynamicMeshComponent

Retrieves (or creates) a vertex attachment component associated with vertex vidx, describing how its motion is driven by the underlying physical system.

Specified by:

getVertexAttachment in class DynamicMeshComponent

Parameters:

idx - vertex index

Returns:

PointAttachment structure

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class MeshComponent

Returns:

static information for all exported properties

setNavpanelDisplay

public void setNavpanelDisplay(CompositeComponent.NavpanelDisplay mode)

Sets the display mode for this component. This controls how the component is displayed in a navigation panel. The default setting is NORMAL.

Parameters:

mode - new display mode

updateSlavePos

public void updateSlavePos()

Updates the mesh vertices to reflect the current position of the attached Frames, FemModels, and points.

Specified by:

updateSlavePos in interface HasSlaveObjects

Overrides:

updateSlavePos in class MeshComponent

updateSlaveVel

public void updateSlaveVel()

Description copied from interface: HasSlaveObjects

Called when the system's dynamic velocity state changes, to update the velocity state of the slave objects.

Specified by:

updateSlaveVel in interface HasSlaveObjects

scaleDistance

public void scaleDistance(double s)

Description copied from interface: ScalableUnits

Scales all distance coordinates.

Specified by:

scaleDistance in interface ScalableUnits

Overrides:

scaleDistance in class MeshComponent

Parameters:

s - scaling factor

transformGeometry

public void transformGeometry(GeometryTransformer gtr,
                              TransformGeometryContext context,
                              int flags)

Description copied from interface: TransformableGeometry

Transforms the geometry of this component, using the geometry transformer gtr to transform its individual attributes. The context argument supplies information about what other components are currently being transformed, and also allows the requesting of update actions to be performed after all transform called have completed. The context is also the usual entity that calls this method, from within its TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method. The argument flags provides flags to specify various conditions associated with the the transformation. At present, the available flags are TransformableGeometry.TG_SIMULATING and TransformableGeometry.TG_ARTICULATED.

This method is not usually called directly by applications. Instead, it is typically called from within the TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int) method of the context, which takes care of the various operations needed for a complete transform operation, including calling TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int) to collect other components that should be transformed, calling TransformableGeometry.transformGeometry(maspack.matrix.AffineTransform3dBase) for each component, notifying component parents that the geometry has changed, and calling any requested TransformGeometryActions. More details are given in the documentation for TransformGeometryContext.apply(maspack.geometry.GeometryTransformer, int).

TransformGeometryContext provides a number of static convenience transform methods which take care of building the context and calling apply() for a specified set of components.

This method should not generally call transformGeometry() for its descendant components. Instead, descendants needing transformation should be specified by adding them to the context in the method TransformableGeometry.addTransformableDependencies(artisynth.core.modelbase.TransformGeometryContext, int).

Specified by:

transformGeometry in interface TransformableGeometry

Overrides:

transformGeometry in class MeshComponent

Parameters:

gtr - transformer implementing the transform

context - context information, including what other components are being transformed

flags - specifies conditions associated with the transformation

copy

public SkinMeshBase copy(int flags,
                         java.util.Map<ModelComponent,ModelComponent> copyMap)

Overrides:

copy in class MeshComponent

getSurfaceMesh

public PolygonalMesh getSurfaceMesh()

Description copied from interface: HasSurfaceMesh

Returns the surface mesh associated with this component, or null if no mesh exists. If multiple surface meshes exist, this should be first one in the array returned by HasSurfaceMesh.getSurfaceMeshes().

Specified by:

getSurfaceMesh in interface HasSurfaceMesh

Returns:

numSurfaceMeshes

public int numSurfaceMeshes()

Description copied from interface: HasSurfaceMesh

Returns the number of surfaces meshes associated with this component, or 0 if no meshes exist. If HasSurfaceMesh.getSurfaceMesh() returns null, then this method should return 0.

Specified by:

numSurfaceMeshes in interface HasSurfaceMesh

Returns:

number of surface meshes associated with this component

getSurfaceMeshes

public PolygonalMesh[] getSurfaceMeshes()

Description copied from interface: HasSurfaceMesh

Returns an array listing all the (non-null) surface meshes associated with this component, or a zero-length array if there are none. If HasSurfaceMesh.getSurfaceMesh() returns null, then a zero-length array should be returned.

Specified by:

Returns:
